There’s an easy way to switch back to using Windows as the default.
You will need to change that number 0 to match the Windows boot section.
Typically it’s always going to be 4 on a default dual-boot configuration.
Change this value to 4, and then save and reboot your machine.
You should go into Windows instead of Ubuntu automatically.
Note: The blocks at the bottom of the file match the items in the menu.
